            <a name="filesystem_max_file_size_limitations"></a>To work

higher limitations.<br>
            <a name="fat_max_file_size_limit"></a>With modern
filesystems designs, usually allowing theoretical 64 bit file
size (16 exabyte), the limitation is often in software implementation
of max file size and max volume size rather than in format design
itself - but unlike older 32 bit variables based designs, filesystem
limitations usually exceeds user's needs.<br>

are for example NTFS, default for modern Microsoft
Windows systems, FAT32 for legacy Windows systems, exFAT for USB flash
drives and SD cards (FAT32 and exFAT are popular on media that needs to
be shared between Windows, Linux, and Apple operating systems), ISO and
UDF for CD, DVD, Blu-Ray and other disk formats.<br>

with newer ZIP64 specifications meant to transparently expand zip
format features, as well as powerful formats like 7Z, PEA, and TAR,
designed for managing large files compression and archiving.<br>
PeaZip also supports extraction of RAR and ZIPX formats, which are
equally desiged to work on large files (over 2^32 4 GB / 2GB limit).<br>
In any case handling such large files with any software utility, and
under any Operating System, requires working on a suitable filesystem,
like as NTFS or exFAT.<br>
